The red power bricks unlock items you can purchase in the cantina (like the Mini-Kit Detector).

Right. I've unlocked and bought quite a few, but really haven't noticed any difference during game play. For instance, invulnerability (which I've bought,) the only character's that are invulnerable are the ghosts which I assume are built in to the characters.

Right, and thanks to a door to door salesman, I figured out how to turn the abilities on after I purchas them. I has rearly put the game on pause, so never noticed the option.

Last night I found the last of the medkits. Ironically, I only used the detector for three, and all three were in ANH. The detector brick was the last orange brick I found. I muct have circled Luke's x-wing on Bespin a hundred times before it finally caught my eye.

All I have left are the three super stories and whatever gets unlocked after that.

Deanna, I'll do ESB first and make notes on Dagobah. I know the area where that last one is at, I'm trying to remember the trick on getting it.
